I stepped into them and pulled them up and adjusted them to fit nicely.My tiny dicklette was throbbing and the head was poking out the top.I reached f...r the nightie and another quick glance i noticed he was rubbing his package as he watched the show.I slid on the nightie down over my smooth body and turned slightly to look in the mirror,everything was in place. I took another quick look out my window to see if he was still watching my sexy show for him and ....he wasn't there.I thought to. I was findingI was quite turned on and my cock already hard lay in the crackof her ass. I then guided my cock into her wet pussy. She squirmedin mock protest but I held her firm. Sliding my cock intoher I began to thrust and stab my cock into her. She gruntedand attempted to fight but I buried myself deep into her.She whimpered and quit fighting and I felt her relax. I maintainedmy grip on her and continued to fuck her like this from behind.“Yeah you like this huh, is this how you fuck your. Liv kept inching closer to us, watching Heather get double penetrated. She started to cup her breasts, and pulled on her nipples.“I’m cumming!” Heather cried out as Kyle grunted hard. The girls stopped and watched her. I could feel her juices splatting all over my balls. I leaned down and told Heather I was close.“Cum in my ass, baby!” she told me, riding Kyle even harder. He grunted again.“That’s it, sweetie, take our loads!” Kyle told her as both of us came in her at the same time. I could. She got up, walked over to her dresser, opened it, closed it, and when she turned around, I saw in her hand a condom package. My teenage step-daughter stood there, naked, in front of me, offering me a condom, and telling me straight-forward that she wanted to have sex with me.I stopped. Stunned. Speechless. Nervous. Naked. And more sexually stimulated than I had ever been in my life. The fantasies that I had through the years, the perverted, sexual and deviated thoughts, and the dreams I had.
